ACID-FORMING STREPTOCOCCI AS INDICES OF FOMITES POLLUTION

Streptococci as indices of pollution in well-waters.

Writing pens as fomites in hospital.

available method used for diagnosis of tuberculosis. Though direct smear microscopy has the advantage of being simple to perform, rapid, less cumbersome, and above all it is inexpensive it has a major disadvantage of having a discouragingly low sensitivity. Therefore, if only direct microscopic method was used for diagnosis, around 22.6% cases with lower AFB counts would have been missed in our...

Characterization of 'faecal streptococci' as indicators of faecal pollution and distribution in the environment.

The recent revision of the taxonomy of 'faecal streptococci' prompted us to verify the importance of identifying the species of this group of cocci. During a study carried out to assess the hygienic quality of environmental samples from a variety of sources, we isolated 198 strains named faecal streptococci on the basis of conventional international tests (EVA broth multiple tube test) used for...

Nosocomial infections in the ICU: Pens and spectacles as fomites.

Nosocomial infections are a major cause of morbidity and mortality. Non-medical objects known as fomites may have a role in their genesis. We investigated the significance of writing pens and spectacles as fomites. The study was conducted at Aga Khan University Hospital, Karachi, from July 2013 to September 2013. Cultures were taken from pens and/or spectacles of resident nurses, doctors and nu...

Responses of Accessions of Zea Mays to Crude Oil Pollution Using Growth Indices and Enzyme Activities as Markers

The performance of every plant in an environment is an indicator of how the plant can withstand the various environmental conditions. This study investigated the toxicity of crude oil on the growth performance, chlorophyll contents, enzymatic activities and oxidative stress biomarkers of eight accessions of Zea mays. The growth enzyme (amylase and invertase) activities, as well as oxidative s...
